Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425620, here are decompositions:
- 13 + 2147425607 = 2147425620
- 29 + 2147425591 = 2147425620
- 61 + 2147425559 = 2147425620
- 79 + 2147425541 = 2147425620
- 89 + 2147425531 = 2147425620
- 101 + 2147425519 = 2147425620
- 107 + 2147425513 = 2147425620
- 113 + 2147425507 = 2147425620
Showing the first eight; more decompositions exist.
